摘要
以电解质溶液一章为例,将物理化学教材中的表格数据进行多样化处理,结合离子电迁移率、迁移数以及平均活度因子等知识点,尝试运用数据补充、图象曲线处理、数据差值计算等方法,并进行综合应用,引导学生从更直观的角度主动思考和深入分析,从而加强对理论知识的理解。
Taking the chapter of electrolyte solution as an example, multiple kinds of treatments on the data listed in tables in physical chemistry textbook are introduced in this article. Data supplement, diagram with curves, data difference calculation and the corresponding integrated application have been used to analyze the corresponding topics, including the ionic mobility, transference number and mean activity factor of ions. Based on the treatments,active thinking and in-depth analysis from sensitive view can be achieved for the students, and the understanding about theoretical knowledge can be enhanced.
